This does not seem to us specilically distinct from V. /'tisf'tmt, 

 hut is separated from that species hy Saccardo, on account of the car- 

 honai'eous stroma and umhilicate disk. ."^pecc. from Farlow do not 

 agree with the description juiltlished. liaviug the stroma much larger 

 (3 mm.-l J, cm. diam.), and where the hark has fallen away, with the 

 margin altrupt. The outer layer in these denude(| stromata is suh- 

 carhonaceous. which results apparently from exposure, the inside i)eiuti' 

 of the usual coloi' and consistence. The same sultcarhouized sinface 

 has heeu noted in specc. found at Xewlield, X. J., on decorticated 

 limits of apph^ trees.
